CAR-COUPLING.

Specification of Letters Patent No. 26,990, dated January 31, 1860.

To all whom it may concern:

Be it known that I, JonL Hoon, of the city of Milwaukee, in the State of Wisconsin, have invented a certain new and useful Improvement on Car- Couplings; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters and marks thereon.

In car-couplings it is very desirable that the draft-bar and the parts constituting the coupling attached to it should possess vertical adjustment, and that the end of the draft-bar to which the coupling is afiixed should, also, have a certain amount of play within its guiding frame. It is, also, equally desirable that the partof the coupling which is made up of the key or bolt and the means for raising or lowering it, should be, to a certain extent, operated by the cars coming together, and yet have full and perfect security for keeping the connecting link from slipping out of place. In getting up my invention I have endeavored to supply the wants thus named; and to this end my invention relates, firstly to the vertical adjustability of the end of the draft-bar with the coupling means, and, secondly, to the so connecting of the bolt or coupling-pin with the means that: attach it to the end of the draft-bar that it may be, in part, oper ated by the cars coming in contact.

Of the drawings forming partof this specification, Figure 1 is a front view of a part of a car frame with the draft-bar and coupling means; Fig. 2, a side view of the same; Fig. 3, a top view, and Fig. 4, a. longitudinal View in section.

In each of these figures like parts are indicated by like letters, the end beam of the car being marked (A) the draft-bar (B) the parts of the coupling frame or box (b, If, Zffl), that marked (5*) being the hunting piece; the stop or guide piece (6 the link for connecting the cars (L) the guiding and adjusting stirrup (S) the bar to which the stirrup is attached (S'); the friction roller of the stirrup (1'); links connecting the stirrups bar to the levers (c 0,) the levers for elevating and lowering the stirrup (Z, Z) the service or thrust pin (P); the king-bolt or coupling pin (K'), the arm to which it is hinged (K and the point of its hinged attachment to the coupling box (K and the slots of the c(oupling box in which the king-bolt slides The construction and arrangement of the several parts being clearly shown by the drawings, the operation will readily be seen. Thus suppose the parts to be in the position shown by Fig. 4:, the draft-bar with the coupling having been adjusted to the proper elevation and the king bolt or coupling-pin elevated so that its lower end rests against the service pin and upon the top edge of the slot of the box or coupling frame one of the links for connecting the cars being within the coupling box; now as the pin of the coupling box, or the butting piece, of the one car hits against the pin or butting piece of the other car the coupling pin will be moved inward and drop down the slot and through the link and thus secure the coupling. The position of the arm (K facilitates this movement of the king-bolt as its weight aids in the falling of the bolt, as its position formerly assisted in holding the end of the bolt against the service pin. As is indicated by the drawings, a chain may be attached to the upper end of the arm (K by which it may be elevated when required.

It will be noticed that the stirrup embraces the draft-bar, that it has a friction roller at its lower end, and that the bar of it is connected by links to a lever on either side so as at all times to allow of the ready adjustment of the draft-bar and coupling. It will, also, be noticed that in lifting up the lever and the coupling-pin the lower end of the coupling-pin comes in contact with the inner end of the service pin and forces it outward, the coupling-pin thus answering to place the service pin in the proper position to be acted upon when the cars come together and to act upon the coupling-pin so that it will drop in the slot.

Having thus fully set out the character and operation of my invention What I claim its rollers and links and levers in relation as new and desire to secure by Letters Patto the draft-bar so that the bar may be ad- 10 ent is, f justed as described.
